The world’s second largest brig has arrived for the Mayor’s Thames Festival, which takes place from Saturday and I was lucky enough to be invited aboard.

At 40m in height, with a bust of the famous composer, an incredible 23 different sails and more than 130 guide ropes attached, it’s an impressive sight.

The young and enthusiastic crew – all students from Poland – will entertain Londoners and visitors with traditional dances, songs and acrobatics as well as guiding visitors around the ship during their stay in London.

Mr RafaÅ‚ Szmytke, President of the Polish Tourist Organisation said:

“They’re the best of the best, hand-picked finalists of a national competition. They are young, creative, and passionate about telling the world about their cities, regions and the country.”

I spoke to crew member Michael Szynkarzynshi who told me:

“The whole course took about three months and there were almost 70 students from all around Poland from at least 75 universities and we were specially picked.”

He added “We had to send a special one-minute video presenting ourselves and the most interesting people were chosen.”

The students will be teaching visitors the Polonaise, a traditional Polish dance, leading up to a Guinness World Record attempt for the most people dancing the Polonaise at one time on Sunday 12 September.
